The purpose of this program is to display crystal
structures on ordinary computer hardware and operating
systems. Four forms of graphics are produced: (1) an openGL
window for immediate viewing, (2) the Persistence of Vision
Ray Tracer (POV-RAY) scene language for publication-quality
drawings, (3) the Virtual Reality Modeling Language (VRML)
for dissemination across the Internet, and (4) a Postscript
rendering of the OpenGL window for those that want
high-quality output but do not have POV-RAY installed.

The current program is an outgrowth of a former version
named crystal that was written by Finger for the
proprietary hardware and software of Advanced Visualization
System.
